When I install them through the command line and finsih up with "nvidia-xconfig" it tells me it can't find my xconfig file. The driver installs but no X on reboot.
How do I properly install my Nvidia drivers? I have Geforce GTX-760.

Most of us use sgfxi, following the on-screen prompts. Basic directions from the Users Manual:

From your desktop:
Press Ctrl-Alt-F1 to get to a terminal prompt.
Log in as root (su and password)
Type: sgfxi

At boot:
Type e when on the GRUB menu to be able to edit it
Add “3” to the end of the kernel line in GRUB’s menu entry for MX Linux
The system will boot directly to the console.
Log in as root (su and password)
Type: sgfxi
